Accredited Drug Testing offers comprehensive hair follicle testing services in Woodlawn Heights, Indiana. For hair or alcohol testing, our specialty lies in hair testing, and we have centers across the nation ready for hair sample analysis. A minimum of 1.5 to 2 inches of hair from the scalp or body can be used. These tests reveal the presence of drugs, alcohol/ETG, and other specialized testing options.
Hair follicle drug tests have gained prevalence recently. This alternative to urine testing is now demanded by various employers, courts, and substance abuse experts. They favor this method for its stringent policies against drug use. Its chief advantage is an extended detection timeline, generally covering up to 90 days, with an observed collection method that is virtually foolproof. However, it’s noteworthy that urine tests remain optimal for detecting very recent drug use, within a five-day window.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. This method captures biomarkers within the fibers of the growing hair strand, providing a long-term history of substance use. When sourced close to the scalp, hair offers a detection duration of up to three months for alcohol and other substances. Collecting hair is straightforward, challenging to tamper with, and easy for transportation.
A sample measuring 1.5 inches, consisting of around 200 strands (similar in size to a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for testing and verification purposes. For tests involving EtG, add-ons, and/or panels exceeding ten, 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. In the absence of scalp hair, an equivalent quantity of body hair may be used. References to head hair pertain to scalp hair, while body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a sample into a lab's system. This step involves checking that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not included in an electronic chain of custody system.
Screening provides a quick efficiency check for drug abuse indicators. While Screening offers a cost-effective means to exclude drug usage in most samples, a confirmed positive outcome is necessary for legal validity. Samples deemed presumptively positive in Screening need secondary verification.
Should a sample test positive in the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. Drugs are extracted from hair at a concentration lower than in alternative methods (such as urine or oral fluid), accounting for hair drug testing's complex nature.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive are cleansed prior to confirmation if necessary. The laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
